Up/Down Ratio

The Up/Down Ratio indicator shows the relationship between the volume of advancing
issues and the volume of declining issues. Upside volume is simply the sum of all volume
associated with stocks that closed up in price, while downside volume is the sum of all
volume associated with stocks that closed down in price.

BigCharts calculates the Upside/Downside Ratio for all markets and automatically selects
the appropriate market indicator for your focus security. For example, if you are analyzing
a chart on IBM which trades on the NYSE, and you choose the Up/Down Ratio indicator, the
system will automatically apply the Up/Down Ratio for the NYSE.
